# ============================= # Private test set nicklas2.tst # These tests are from 9x9 games. # None of these tests passes with version 2.7.222. # I think these problems are "simple". # ============================= #CATEGORY=ATARI_ATARI #DESCRIPTION=GnuGo misses followup to D4 push-through. #SEVERITY=1 # This is not as clear cut as it may seem. 2.7.228 values the endgame # move at A7 to 6.66 points which seems about correct. The fact that # white D4 threatens both to cut off E5-F6 and to capture D3 through # a chain of threats (which is what happens in the game) is not that # easy to understand. A more general atari_atari module could # perhaps see it, but we are still far from that. I think this test # should be in nicklas3.tst (harder problems). loadsgf games/nicklas/nicklas1.sgf 29 102 reg_genmove black #? [D4] #CATEGORY=PATTERN_TUNING #DESCRIPTION=I think G9 is not too terrible here. Very difficult to see.-trevor #SEVERITY=1 # This test illustrates a general weakness of GNU Go: It's poor # ability to defend its borders. White can enter blacks domains or # capture the E8 group. In the latter case, whites first move is # a sacrifice and the capture happens through a chain of threats. #Added E6, still not thinking G9 is so bad. -trevor loadsgf games/nicklas/nicklas6.sgf 23 601 reg_genmove black #?
